I'm plumbing in an oil thermostat into my -12 for the upcoming winter. It will hold the temp at 205F before diverting the oil into the oil cooler.
There is limited space under the cowel so the routing of the hoses is problematic at best. One possible solution would be to use a 180 degree #8 AN racing fitting. This would avoid a good chuck of hose, but the fitting is an aluminum AN fitting used is racing applications.

The question is Rotax is not excited about tight 90 degree turns, but "sweeping turns" is acceptable. I assume that is due to the tight turn and the fluid hitting the "back side " of the fitting causing friction.
How would the 180 degree fitting perform? Any problems? The guys who sell them say the friction loss is comparable to a 45 degree AN fitting. Anyone have any data or comments on this fitting on the "hot oil" side of the thermostat. The hot oil should flow easier than the cold oil.
